with respect to the center of mass the speed of each particle is (Gm/4R)1/2 as their is no external force acting on the system so velocity of the center of mass is zero velocity of each particle is (Gm/4R)1/2.

mv2/R=Gm2/(2R)2

The gravitational force of attraction between the two masses is

F = Gm2/(2R)2

This force provides the necessary centripetal force

mv2/R = Gm2/4R2

v2 = Gm/4R

v = √(Gm/4R)

The Speed will be equal to their velocities in inertial frame itself as there centre of mass will be stationary.

Here center of mass will be stationary because both particles are having same mass,Therefore ,Speed of the particle will be as equal as critical velocity of the particle...Therefore answer is √GM/R

Two particles of equal mass(m) go around a circle of radius R under the action of their mutual gravitational attraction.Here center of mass is stationary because both particles are having same mass.1/2√(GM/R)

Hello this is master Yug Dedhia
Here,using theory of gravitation
Therefore,mv^2/ r = Gm^2/(2R)^2
Thus the answer is v=√(Gm/4R)
Thanks
